The Vernal Equinox on Wednesday evening coincided with the rise of a supermoon. It’s the third supermoon of the year; and to have one come on the same night as the Equinox is rare indeed. It last happened in 1905 and it won’t happen again until 2044. And I was there, on top of a hill in Cesar Chavez Park, doubting whether the moon would penetrate the layer of clouds over the Berkeley hills — until it did. The moon had a clear gap between the ridge and the bottom of the clouds, and then went dark for a while, until it re-emerged into an almost totally clear sky. Here is a video of the supermoon’s first two minutes, speeded up to fit in one minute for all you very busy people with short attention spans.
